Age is probably sticking. I have an 05 670 d12 465 volvo 1.5 mil. On it 5.5 to 6.2 mpg never smokes. The epg that controls the exhaust shudder might be sticking. Closed it has 2 functions one is to be used as an exhaust brake and second is as a backpressure device to increase exhaust to the egr valves. The "twins" as I have read are very problematic.

Hello everyone, I have a couple questions about my volvo. I've owned it for years, and it's been blowing out black smoke past 15 pounds of boost. I've replaced dozens of parts. Egrs, 1 injector, boost sensor, turbo seals, exhaust manifold and gasket, harness, overhead. The truck runs great no misfires or anything has power fuel mileage isnt the best I'll get around 5.5 with 40k pounds. The only code that's ever popped up is egr value too high besides that I havent had any problems. I would like to see if anyone has any ideas to what it might be?

If your boost is good under load, 32lbs approx, then you have egr issues. Bypass the egr. OTR sells a bypass module, fairly easy to install. No more egr bs.

Otr doesnt sell the modules anymore to people in the U.S.
